In American English, "coming out" has a very specific idiomatic meaning: namely, proclaiming one's homosexuality openly. The idiom is related to the idiom that a secretly gay person is "in the closet (about being a homosexual)" In fact, this idiom is the vastly predominant meaning of "coming out" in American English. Is this Hungarian sentence ever used that way?
It's OK. They just haven't consistently accepted "also" as a synonym for "too" in every sentence yet, so just report it when it happens.
